Specification of `Letters Patent.

Application filed January 2, 1912. Serial No.` 668,996:

To all 'whom t may concern: p

Be it known that I, JAMES B. MILLER, a

siding at Kent, in the county of Portage and State of Ohio, have invented certain new and useful Improvements in Combination-Locks; and I hereby declare the following `to be a full, clear, and exact description of the invention, such as `will enable others skilled in the arttofwhich itypertains to make and use the same.v

This invention: relates to `new `and useful improvements `in locks and particularly `to the class of locks known as keyless locks or combination locks. i y

vide a lock wherein the means for actuating the lock bolt operatingmechanism from the `outside of the door is separate and independent from the means for operating `the mechanism from the inside of the door.

With these objects in view `and to the end of securing other advantages `hereinafter `appearing this invention consists` in certain features of construction and combination of parts, the preferred form of which isillus-` trated in the accompanying` drawings,

pointed out in the claimsand describedin the specification.`

In the accompanying `drawings `Figure 1 is aview of the lock with one of the faces of the casing `removed showing the lock bolt in its outer position and the other mechanism in position for holdingit against movement. Fig. 2 is a section on line 2 2, Fig.` 1. Fig.` 3 is .a detail view showingthe position of the `bolt operating mechanism when movedi by the inside latch to open the door `from the inside. Fig. 4 is a view similar toLFigul showing the position of the mechanism when the combination has been operatedto lift the tumbler so that the bolt can be operated from theoutside of the door. Fig. l5 `is a similar view toFig. 3 showing the position of the bolt operating mechanism whenmoved bythe outside latch to open the door from the outside.

mortised to receivethe end of the bolt and casing is similar to the usual lock casing and has a top and a bottom 2 and 3respect1vely`, an inner and outer side 4 and 5, respectively, a back face 6 formed integral with the sides and a front` face 7 which is formedseparately and is removably `secured to the rest of the casing :by means `of screws 8 which screw into lugs 9 formed onthe inner surfaceiof;

170 i casing near `the bottom thereof are formed the back face 6. In the faces 6 and 7 of the openings 11 and 12, respectively, and in the door below said openings isformed anopeni ing 13, the object of which will appear later. Within and `near the center of the casing is arranged the lock bolt 16 which serves also as the latch, `but the sides of the bolt arei parallel and at `a right angle to the edge,

the bolthaving no beveled face as is custo-` arranged to project at the proper angle to engage the `bolt and shove it back when the bolt `is being used as a latch. The bolt 16 mary with latches, and the lock strike 0 is is provided with a longshank 17 and at the free end of the shank 17 is arranged a lug 18.

formed `a groove 2O adapted to receive the shank 17 so that said lug `forms a guide and support for the said shank 17. A coilspring Patented Apr. 22,1913.

le5 On the innersurface of the face 6 of` the casing is arranged a lug 19 in which isl 21 is arranged on the shank 17 and one end thereof abuts `againstthebolt and the other end abuts against the lug `19, the arrange` ment being such that the tension of the spring will force the bolt to its outer posi tion so that the bolt can `serve as a latch when the locking mechanism is thrown 0E.

On apin 23 is fulcrumed the bolt operating lever 24. This lever has two divergent arms 1 25 and 26.` The arm 26 extends up above the shank17 and is provided with a small flange `27 which engages with the lug `18 on the `end of the shank 17 The other arm 25 extends. 1 downwardly and `is provided with a flange 28.`

j It will be readily seenthat when the arm is moved up thek arm 26 is moved back into engagement with the lugy 18 on 'the end of the shank 17 and thereby the lock bolt is drawn back to its unlocked or inoperative position against the tension of the spring 21. A lever is pivotally supported atone end on a pin 29 and the free end of said lever extends under the iiange 28 onthe arm 25 and across the openings 11 and 12 in the faces of the casing and above the opening 13 in the door. A lever 31 is alsoV mounted on the pin 29 and said lever extends alongside of the lever 30and the'end-thereof also extends under the flange 28 of the.` arm 25 and this lever-31 is not quite as l'ongas the lever 30, thelendof` the said lever 31 terminating a" short distance back of the end of the-lever 30. 1n the opening 13 of the door, at the inner side of the door, is pivotallymounted a thumb lever 34 and the inner end of said thumb 'lever extends under the end of the lever 30 whereit extends -be-A yond the end of the lever 31 and in the same opening 13 at the outer sidefof the door is pivotally mounted a thumb lever 38 and the inner end thereof extends under both the lever 30 and the lever 31.( It will therefore be understood that when the thumb lever 34 .arm` 26 to swing back which draws back `the bolt 16. Now when the thumb lever 38 at the outside of the door is pressed down it will raise both of the levers 30 and 31 bringing ,them into contact with the flange 28 on the arm 25, which again causes the 'arm 25 to swingvup and the arm 26 to `swing back drawing back the bolt 16. kThe bolt 16 can therefore be drawn back by operating the-thumb' lever on the inside of the door or the thumb lever on the outsidel ofthe door and each lever operates independently of `the other lever. The lever 34y at the inside of the 4door is always left free to operate the bolt but means is provided to prevent the operation of the lever 38 on the outside of the door when it is desired to lock the door which is arranged as fol-l lows -On the lever 31 is arrangeda rigid arm 40 which extends up beyond the shank 17 of the bolt 16. An L-sh-aped tumbler 41 having` a flange 42.at its uppercend and iange 43 at its lower end is arranged to slide vertically and is held against displacement by a lug 44. When said tumbler vis inl its lower position the flange 43 at the end of said tumbler is arranged to lie inthe path'of the rupper endv of the arm 40'of the lever 31, `preventing any movement of the arm 40 and consequently any movement `of the lever 31 and therefore any operation of` the thumb lever 38. A spring'45 is arranged the tension thereof `normally holds the tumc .i

Vbler in its lower position.

The means for lifting the tumbler is ed inthe casing and extends outwardlyto the outside of the door and on the vouter end thereof is secured a knob 51.' On the spindle t within the casing is secured a combination disk 52 so as to turn when the said knob is Vturned. Onthe face of said combination disk 52 are arranged-,a series of cams or n' ridges 53.' 'Aflever 54 is ivot-ally mounted at one end at the side o saidcombinatiom disk and extends across the face ofvsaiddisk. and the free end thereof extendsunder the l.

'70,. arranged as follows: A spindle 50 1s mount y soy flange 42 at the Aupper end kof the-tumbler 41. A peg 56 issecure'd on the lever54 and"- extends in toward Vthe -face `of theldisk 52 so as to come inv cont-act with 'the ridges "53 thereon.

The ridges are so arranged'thatA when the combinationdisk'52 is turnedtback Y and forth through'a whole or part of a revolution a number oft-imes,` accordingto a predetermined plan, the peg^56 travels 1- from ridge to ridge constantly `r'novng* fary ther from the center ofthe diskVwhich of'- course causes t-he lever 54 to move upward and the free end .of said; lever 54 comes 1n contact with the flangel 42` onl thestumbler 41 and raises the said ltumbler. lso lthatL the lower end thereof isremovedfrom the `path of the arm 40 freeing; said arm. The lever 31 is then'free Ato move which permits the operation of the latchfrom the-outside `of the door.

Around theperimeter of the disk:

52 are formed a series of notches .andfl' at therside lof saidk disk 52 fis' arrangedy a y spring 5.8 which is supported lby lugsg9 and.`

ne end of the spring 58 is held inw.

contact with the perimeter of the diskV 52' and when the said disk 52 is turned the end of vthe spring 58 passes i over the notches 57 and indicates both to the senseof hearing` and to the touch through what Vpart of.` revolution the said disk 52 has been turned. f To destroy the combination after it has been worked, the following arrangement `isprof videdz-On the bolt 16 is secured a finger 70 and on the combination disk 52 is mounted a stud 71 which is so located on the disk 52 that when the combination `has been worked the said stud 71 will .be opposite the end of the linger 70 -and whenthe said boltis drawn back` the finger V70 will come .inv

contact with said' stud andk turn the'fsaidv ldisk 52 destroying the combination. n

In yorder that the lock ycan be \used .asa

latch andoperated from .the outside of the. vdoor without workingthe combinationrthe following arrangement.` is provided :-In the front sidefof the casing above the bolt 16 is formed .a ysmall vopening 60 and over said opening] on the kinsidetof the casing is arrranged a `small plate 61 which iis `provided with a small lug `62 which `extends outwardly through said openingOiand on the inner face of said plate is formed a socket 63. A dog 64 is pivotallymounted `in proximity to the plate 61 andoneendoii said dogex-` tends under a flange 65 formed on the tumbler 11 and at its other end said dog is provided with a stud 66 which extends into ithe socket 63 in the plate 61.` A coil spring `67` is arranged on the stud 66 between the plate 61 and said dog to hold the plate in position. Now when it is desired to use the` lock simply as a latch the plate 61 is engaged by the lug 62 and is moved down, whichby its engage-` ment with the dog `64causes the opposite end of the dog to swing up lifting up the tumbler 41 and holding the flange 43 at the end thereof out of the `pathof the arm 40 on the lever 31 so that the thumb lever on the outside of the door is freeito operate.
